Initially, the term portal was used to refer to well-known Internet search and navigation sites that provided a starting point for web consumers to explore and access information on the World Wide Web.
Portals are often the first page the web browser loads when users get connected to the Web or that users tend to visit as an anchor site. They offer users a surplus value of service based on the features of classic search engines: a well trained concierge who knows where to search and find; a well-assorted newspaper kiosk that keeps the latest market information about the surfer's personal stocks ready; free communications possibilities like email or discussion boards.
